To all iti/rom it may concern:

Be it known that l, DANiEL SHAW VlT/iieii, :i citizen ol the UnitedStates, residing` :it Denier, in tlie county of Denver and State of Colorado, lieve invented e new and useful Motive-FluideOpernteil Tool, of Wliicli tbe following is :i specification, i

The present inveniion relates to motive iluid operated tools, :indniore pertieuiery tlioeeol' the type employing automatic oonlrolliiig Valves.

Une of tlie priiiiery objects oi the present invention is to provide novel and eiective means for securingn e portion of tlie return stroke oi' the piston or liniiner by tlie eX- pensive loi-ce oi tlie motive fluid, tl'iereby etlectingr e saving in motive fluid and ninterielly reducing tlie sliooks end Vibrations.

A. lu'rtlier iiiiportzint object iS to 'provii'lein -lilie tool7 :i reserifoir lor motive fluid, to' wliicli reservoir :i constant supply of iiiotive fluid is direil :1nd from Wliieli the Worlii'igir parte su "ed iiliod while the tool is in operetion7 ille arrangement permittingT the ueeoi :i conipfiriitively siiizill liose and decidedly inrreiieiug the working capacity el the mii4 chine.
